My dad in Iowa caught this in a leg trap. Something was getting his guineas excited at night which then got the dogs going. He set up a trap and this is what he got. He moved it into a dog cage and took pictures. He ruled out a dog (wrong frame structure) and a fox (too big). He got the local vet involved who told him to kill it and burn it right away. He said that it was about 3 foot long and guessed it would weight 30 pounds if heathy. The animal was docile, maybe because it was sick. He lives in the country with a large river within a mile. Any ideas?
